Practice exercises

Swift Macros is a complex topic, and it is a challenge to understand how to create a Swift macro without trying it yourself. Here are two exercises that can help you get started:

• Create an attached Swift macro that adds a function called printVariables. The function prints the list of the class properties and their values.
• Create a freestanding macro called #colorhex that receives a hex color value and generates an RGB color expression. For example, #colorhex("#FFFFFF") will generate Color(red: 0.0, green: 0.0, blue: 0.0).

In addition, here are some links that can help you get more insights about Swift Macros:

• Swift Macros documentation from the Swift.org projects: https://docs.swift.org/swift-book/documentation/the-swift-programming-language/macros/
• A GitHub repository about great Swift macros we can use and learn from: https://github.com/krzysztofzablocki/Swift-Macros
